First post here, and very new. Here to learn.
I am using this header only library [SQlite ORM][1] in order to input standard c++ data types into an SQlite database. I am happy with the functionality, but I get a whole host of warnings from my compiler (Code::Blocks running on Ubuntu). It has done this since I started using it, and am wondering if I am doing something wrong.
Please let me know if there is something I need to to do to address these warnings.
